The present invention relates to a repair and reinforcement device for a retaining wall formed in civil engineering such as construction and roads.

In general, when the road construction passes through the mountains or slopes, the retaining wall for opening the road or the retaining wall for the foundation part in the building built on the slope is composed of the outer wall surface which is fixed with cement mortar to reinforce the slope to reinforce the slope. Retaining walls are being used.

That is, even in hilly land, due to the densification of residential environment due to the efficient use of land, the sloped soil is cleared in an appropriate horizontal state, and then the facilities such as buildings are constructed, and the passage spaces or roads are opened accordingly. As a result of the development, when roads such as highways pass through the mountainous area, a construction such as a retaining wall is required.

In addition, in the city, such as a high cost of land to build a dense building or grievous building, it is necessary to install the retaining wall in order to increase the efficiency of the land.

In addition, the retaining wall of many parts is a retaining wall that is supported by groundwater that seeps into the walls of the retaining wall, or the load of the building or the inclined soil is infiltrated by rain, such as heavy rain. There were many cases of collapse.

However, when the retaining wall described above is collapsed by the clavicle or the like, the soil filling the inside of the retaining wall due to heavy rain, leakage of groundwater, or the like, or the inclined soil of the road is pushed down by heavy rain, or by the weight of the building. As the outer wall surface of the retaining wall supporting it collapses, the whole structure of the retaining wall collapses. Accordingly, when the retaining wall is left unattended for a long time, the soil is collapsed on the road, the building is inclined, or the building sometimes collapses. It was often the cause of accidents.

In addition, the repairing method for the conventional retaining wall collapsed as described above is often repaired by putting sand or soil in the bag, and then stacking it in the form of an embankment or retaining wall while forming a slightly inclined surface. There is a problem in reinforcing the bearing capacity for photographic soil, and there are also many limitations in preventing the collapse of rainwater due to heavy rain.

In addition, the installation of the reinforcing wall reinforced with reinforcing bars and cement mortar is assembled into a plate-shaped foam (form) on both sides of the retaining wall wall and filled with cement mortar for a certain period of time, and then the used plate-shaped foam (form) As the burden of the process to separate and re-install), the economic burden is weak due to the high cost burden on the repairing process.

In addition, according to the original application of the invention, the cylindrical formwork is overlapped with each other in the shape of a wall and filled with cement mortar in the inner space thereof for reinforcement of the retaining wall, wherein the cylindrical formwork used here is perfectly assembled with the retaining wall structure. The outer wall surfaces of the cylindrical formwork for filling the cement mortar, which is a reinforcement in the inner space, are assembled to one side formed in an arc shape, so that the assembling structure of the assembling grooves thus formed is simply assembled under adverse conditions in the construction site. In many cases, it is desirable to provide an effective structure that provides robustness.

The present invention is a simple assembly in the arc-shaped assembling process, which is a joining portion in which the cylindrical form (form) used in the conventional repair process described above is assembled by assembling for the construction of the retaining wall, thereby forming a structure of the retaining wall, which is a reinforcement cement. As an invention for filling the mortar, the invention is to provide a form for repair and reinforcement of the retaining wall is easy to assemble and construct the formwork integrally with each other at the construction site.

The present invention is provided to repair and reinforce the road and civil retaining wall 60 is collapsed or damaged by heavy rain and inclined upper soil as described above, further for repair and reinforcement thereof. In order to repair and repair the retaining wall constructed by digging, the binding bars are assembled to the binding holes formed on both sides to form the retaining wall structure in the form of retaining wall. Insert the reinforcing bar into the inner space, insert it into the cement mortar, fill it with the fluidity of the cement mortar, fill the binding sphere and the binding rod into the inner space assembled by the fixed rod from the formwork, and then cure for a certain period of time. As the invention is configured to form a fill portion by re-mowing the collapsed portion in the shape of a retaining wall, This will be described in detail with reference to the accompanying drawings as follows.
